Dan-You may know this already, but I switch antennas all the time. For on the road, and open country I use an SBB25 for it's range and good gain characteristics. For trail use, I like the SBB1, which is rubbery and flexy so it does not hang up on terrain. Despite it's small size, it does really well.
We had amazing radio coverage this weekend at Wentworth/Rubicon. When we split the group to get the crippled rig off the trail, the two groups were still talking on simplex an hour later. It was only when we came off the trail at Loon Lake, that we had to switch to the 146.805 repeater which has great coverage of the entire area.
Tom posted our experience on the way up-He was on the Richmond-Oakland Bridge, I was in Eldorado Hills, ALvaro was in Georgetown, and Jim was in camp. We were all talking to each other, enough that Ernie heard us in Roseville and joined the conversation. I knew just after leaving town, that Jim had good sites, and there was enough room for all of us, even though I was still 2 1/2 hours out from camp.
